Hi everybody, i'm new to mathematica, and i really need help with a equation system.
the whole system is too long to post it here, so i'll put an example:
if i need something like this to be solved:
f[x_, y_] := x - y + ((x*2)*y - (x^2)/y) == 0
g[x_, y_] := y*x + (Pi*y - x^4 + x*y) == 0
how can i write it? i've been searching for tutorials and this should be a correct form to write it, nevertheless, it says me that "Solve::eqf: 0 is not a well-formed equation."
Thanks for the help
